Real-time reconstruction on micro-CT setup

Dose reduction in computed tomography is one of the most urgent questions with a deep research history. One of the rising potentially powerful tools for dose reduction is monitored tomographic reconstruction. This promising concept heavily relies on utilizing real-time reconstruction from currently available data, which is the main topic of the present paper. The main result of achieving a real-time reconstruction on a commercially available micro-CT setup utilizing SmartTomoEngine SDK is highlighted and presented in more detail. The new acquisition order is proposed, allowing for faster convergence of intermediate reconstruction results. An optimization of reconstruction from partial data is proposed, which allowed the production of 385 and 440 reconstructions for standard and proposed acquisition orders correspondingly during a single acquisition of 512 projections, achieving a real-time reconstruction. The results are produced with the use of only a single previous-generation consumer-grade graphical processing unit. The study results demonstrate that with proposed optimizations monitored tomographic reconstruction can be effectively utilized for practical applications using the current generation of existing setups in the micro CT application field.
